Water Flow Balancing Valves

Circuit setter cb provides cost savings advantages of pre set proportional balance and assures optimum system flow balance at minimum operating horsepower.

Water flow balancing valves.

Most technicians are stronger on measuring airflow than waterflow. Let s take a look at how to measure flow through a water balancing valve. Balancing the chilled water main branches sub branches risers header terminal by proportionally. At each heat transfer coil the balancing valve is set to provide the precise.

The balancing valves used most often are manual calibrated combination flow and balancing devices such as the bell gossett low lead circuit setter. Control valves picv low temperature valves commercial marine products manual balancing components solenoid valves hays fluid controls manufactures automatic flow control valves in imperial and metric sizes which operate over a wide range of differential pressures. With all valves are fully open measure and record the total actual flow rate and compare this with the total system design flow rate. Role of balancing valves the role of the balancing valve is to control the gallon per minute gpm flow rate in each building main riser and branch to deliver the designed gpm flow in chilled and or hot water applications.

The traditional larger system uses balancing valves at or near the end of main. How the test works a balancing valve is a fitting installed in a hydronic system. Hydronic balancing also called hydraulic balancing is the process of optimising the distribution of water in a building s hydronic heating or cooling system by equalizing the system pressure so it provides the intended indoor climate at optimum energy efficiency and minimal operating cost. Venturi valves provide balance ease of commissioning and shut off in a wide range of hvac systems.

To provide the correct power output heating or cooling devices require a certain flow known as the. This short article is intended to introduce the basic principles of balancing valve waterflow measurement. Valves can simply be pre set using the b g circuit setter balance valve calculator curve booklet g10091 or the system syzer application for iphone ipad or pc. Where necessary close the main regulating valve to provide a flow of approximately 110 design flow rate.

Circuit setter rf for low flow applications provides cost savings advantages of pre set proportional balance and assures optimumread more. We offer a line of balancing valves that help heating and cooling systems perform well and cost efficiently. This balance valve allows the plumbing contractor to have the system balanced by throttling the valve. The valves also have a brass venturi flow element for greater accuracy and allow for manual balancing and shut off.
